Power Consumption

Compared to the Intel Atom boards, the Zotac wins out - it doesn't have to use a bulky desktop power supply which isn't as efficient at these low power draws. Compared to something more similar however, like the Atom 230 based ASUS Eee Box with its own external DC power supply, we see that the Zotac Ion does draw more power than Intel's Atom platform. I'm not sure how much more this could be cut down when used in a netbook/notebook, but that could be a deal breaker for more mobile versions of Ion.

Final Words

What do I think of the world's first mini-ITX Atom Ion motherboard? I like it. Zotac did a good job of delivering pretty much everything I'd want in a board like this, going even further than expected and offering a solution with an external power brick. I don't like the external power option from a long-term replacement standpoint, but I do appreciate its convenience. My only complaint is the price, at $189 it's a bit expensive for the performance you get but I do concede that there are some benefits in the convenience department. All you need to add is memory and some sort of storage and you're good to go, you'll have a system that's easily capable of playing back high definition content (not to mention very power efficient while doing it).

The general application performance of the Zotac Ion isn’t actually any better than the Intel D945GCLF2. It’s when you look at GPU-enabled applications that the Ion holds any real performance benefit. Blu-ray playback or 3D gaming are its real performance strengths; if you plan on doing neither then the platform isn’t very useful.

I did try some CUDA applications on the Zotac Ion board and they were definitely faster than using the CPU alone. While our x264 test managed around 12 fps on the Zotac Ion, using Badaboom I was able to encode at just under 20 fps.

When it comes to the Atom processor, at least on the desktop, there’s simply no reason to opt for the single-core model. Most tasks are so completely CPU bound on Atom that any increase in processing power is instantly noticeable. The Atom 330 ends up being faster than even a 1.6GHz single-core Celeron 420 in many tests, particularly video encoding and 3D rendering, while falling behind in other applications like WinRAR and even our general SYSMark tests. With enough cores, the Atom architecture is efficient in delivering good floating point performance it seems. Branchy integer code however favors the speculative execution engines of more conventional desktop microprocessors. The only reason I see the single-core Atom being of any use is if you're building a cheap file server, but otherwise the Atom 330 is so much faster across the board that it's more than worth it. Hyper-Threading definitely helps the Atom 230, but there's no replacement for another fully functional core. The added power consumption is nothing serious.

If you do need more CPU power, Zotac actually offers an LGA-775 version of the board but it of course requires a standard power supply:

Power consumption on the Zotac Ion is appreciably low, thanks in part to its 90W DC power supply. Compared to ASUS’ Eee Box however, the Ion system does use nearly 50% more power under load.

Everyone seemed to want an Ion based motherboard after NVIDIA first showed off its reference platform. Acer delivered the first Ion system, but it looks like Zotac is delivering what we all wanted from the start. Now it's time to see how people start using these things....

    Thanks Anand, will definitely drop you a note regarding this over the weekend. It's quite unfortunate that Zotac left out Wake-On-USB for their 9300/9400 mobos, something many consider essential in an HTPC build.

    If I didn't have so many projects already I'd seriously consider one of these as the basis of a CarPC system. It's not cheap but a good touchscreen car monitor will run you far more.

    On page 5: "Once more, the Pentium 4 gets beat by the Atom 330 but loses to the Atom 230"

    I hope you will review Cortex A8-based Netbooks once they show up. Because Im not impressed at all with Atom, not when looking at <45W dualcore Athlons. Taking into account that those are at 65nm aswell the Atom aint looking that efficient.

    I would take a Celeron 420 any day of the week over an Atom or a dualcore athlon ;)

    "Celery is for eating, not computing."

    Sorry, let me be perfectly clear, I would like a Core2 Conroe-L from 1.6-2.0 ghz (every one I have used will easily go over 3 ghz with no voltage increase)

    Look at the raw numbers between the Atom and the Conroe-L and tell me on a desktop/stationary machine (IE not a netbook) you wouldn't rather have something more than twice as powerful.

    I realize it is called a "celeron", but it is the most freaking powerful (Core2 architecture) Celeron ever sold.

    They cost $25-35 on ebay, the LGA 775 version of this board is only $139. It makes a whole lot of sense if you don't plan on running it on battery power.

    Not to mention you can move all the way up to a Quad if you want, but a $60 e5200 2.5ghz 2MB Level 2 Cache seems like a perfect match.

    Oh, and you get a PCI-e 2.0 X16 slot :P http://www.newegg.com/Product/Product.aspx?Item=N8...">http://www.newegg.com/Product/Product.aspx?Item=N8...

    For $10 more it makes a whole lot of sense. (If you already have the LGA 775 chip laying around it makes even more sense.)

    What could have made this board perfect is a PCI-E slot to stick some decent audio in. Anyone seen mini PCI-E sound cards around :)
  • Visual - Wednesday, May 13, 2009 - link

    Why would you want a sound card for any computer made in the last 10 years? Even with the fanciest card, there would not be even one bit of difference on the digital outputs, which are the ones you should be connecting to your receiver. On the analog outputs there will be quality differences indeed, but if you're using them you deserve what you get :p Besides, I get the feeling you wouldn't notice the difference anyway as if you're that stupid to be using them you are also probably using some crappy speakers.

    "Everyone seemed to want a Ion based motherboard after I first previewed the platform."

    Yeah, it is all because of you :roll:

    Is that x264 encoding that you used to test power consumption? Why that? The most power draw likely comes from the chipset. Test Blu-Ray playback or something.
  • Pandamonium - Tuesday, May 12, 2009 - link

    The first comment was pretty rude and uncalled for, I must say.

    I wanted to see an Ion-based HTPC after the preview and this article confirmed that an Ion-based HTPC is what I should set my sights on next. The only improvement Zotac could have made is to include a PCIe slot for TV tuners, audio, or beefed up video. A higher rated Atom would be nice too, but I don't even know that one exists.
